Stochastic Generation of Particle Structures with Controlled Degree of Heterogeneity

open access: yes, 2010
The recently developed void expansion method (VEM) allows for an efficient generation of porous packings of spherical particles over a wide range of volume fractions. The method is based on a random placement of the structural particles under addition of

Review and Evaluation of Slip-ratio-based Void Fraction Prediction Models

open access: yesYuanzineng kexue jishu
Void fraction is an important parameter in gas-liquid two-phase flow, which is closely related to the flow pattern, pressure drop, and heat transfer of the flow field.

Properties of the most metal-poor gas-rich LSB dwarf galaxies SDSS J0015+0104 and J2354-0005 residing in the Eridanus void

open access: yes, 2013
SDSS J0015+0104 is the lowest metallicity low surface brightness dwarf (LSBD) galaxy known. The oxygen abundance in its HII region SDSS J001520.70+010436.9 (at ~1.5 kpc from the galaxy centre) is 12+log(O/H)=7.07 (Guseva et al.).

Preferential concentration of inertial sub-kolmogorov particles. The roles of mass loading of particles, Stokes and Reynolds numbers [PDF]

open access: yes, 2016
Turbulent flows laden with inertial particles present multiple open questions and are a subject of great interest in current research. Due to their higher density compared to the carrier fluid, inertial particles tend to form high concentration regions ...
